Abstract
An optimal method was presented to prevent the decrease of diffraction efficiency when the infrared diffractive optical elements working in a wide temperature range. The method can lower the cost of thermal infrared diffractive lenses by decreasing the microstructure height and volume of multilayer diffractive optical elements (MLDOEs). The diffraction efficiency of the results was compared to the previous methods with wavelengths between long wave infrared and middle wave infrared. Those comparisons show the better temperature stability of MLDOEs when the elements working in a wide temperature range.
